So the rear tire on Purple Haze, my main road bike, was starting to get a bit thin. How thin? Well, let's check the tire wear indicator divot.
Which no longer exists. Cool. Well I'm sure there's a little tread left, right?
Very, very little.
Alright, it's time to replace this tire. Now this tire is a Continental GP4000s-II in a 25mm width.
And when it's fully inflated it measures...
28mm, not 25mm. This turned out a little awkward last time I replaced one of the tires because I bought a Continental GP5000 in a 25mm width.
Which measures 24mm.
So to get things back on track I got myself a 28mm GP5000 this time.
And it measures...
Hmm, close enough.
As per usual, I put the new tire on the front and rotated the old front tire to the rear, since the front is more safety critical and wears out at a much slower rate than the rear.
So it won't be too long before this 25mm rear wears out and I can get back to 28mm-ish on both ends... which I had spent years thinking was 25mm.
